Application filed August 8, 1912. Serial No. 713,985. I

and specifically and more particularly to builder mechanism for ring spinning or twisting mechanism.

. In the application vof John V.Cunniff, Serial No. 685,030, filed March 20, 1912, there is disclosed and claimed broadly; continuously acting mechanism for windmg yarn packages in the general form of cops or bobbins to secure an increase in gain and preferably a progressively increasing gain throughout the formation of the base of the package, preferably with an undiminished gain throughout the balance of the package, and in combination with an increase in traverse throughout the base of the package and preferably throughout the whole package. In such application, the disclosed embodiment of the invention comprises a single acting traverse and gain controlling mechanism having in combination with the yarn receiver and a yarn guide, a primary actuator lever, yarn guide holding means and connecting and governing devices between said lever and said means cooperatively arranged to secure the above results, and in such embodiment the general mechanism provides for the shortening or taking-on of a flexible element which is one element of said connecting and governing devices. In

the application of John V. Ounniif, Serial No. 706,910, filed July 1,1912, there is disclosed mechanism intended to performrthe same functions that are fulfilled by the mechanism of the earlier application and wherein the flexible element is let of or elongated duringthe winding operation, and also wherein is disclosed a single acting traverse and gain controlling mechanism of simple form, to which existing mechanisms can be readily converted and adapted.

The present invention relates to' the inventions disclosed in said'applications and is intended to present a simple form of single acting traverse and gain controlling mechanism to which existing'mechanism can be readily adapted, although certain features of said invention are of general or broad application and may be employed in connection with winding mechanisms of other types.

In the present application, I have represented the traverse and gain as effected and controlled by take-up of the flexible element, but obviously my invention may be readily adapted to constructions wherein the flexible element is let off, as will be hereinafter more fully set forth. I

In order that the principle of the invention may be readily understood, I have chosen to illustrate that embodiment thereof consisting of builder mechanism for ring spinning frames,that is, a specific application of winding mechanism.

In the drawing-Figure 1 is a front elevation of one form of builder mechanism for ring spinning frames constituting an embodiment of the invention; Fig. 2 is a view of said mechanism partially in vertical transverse section and partially in end elevation; Fig. 3 is a view in side elevation of a portion of the mechanism shown in F ig. 1, upon an enlarged scale; Fig. 4c is a detail, partially in section and partially in side elevation, of a portion of the mechanism shown in Fig. 3; Fig. 5 is a longitudinal trans verse section taken upon the line 55 of Fig. 1, and Fig. 6 is a longitudinal section taken through one of the shafts of the apparatus.

In yarn or thread windings mechanism to which my invention relates, the coils of yarn are laid along the yarn receiver by effecting a relatively oscillatory movement of a yarn guide and the yarn receiver along the latter for a portion of its length, which movement is generally called the traverse; and the resulting at the other end of the yarn package is termed the chase, or the taper; and its terminus the nose of the cop.

My invention provides means whereby the package may be wound and formed with efficiency in a winding or spinning or twist ing machine; and particularly in a spinning or twisting machine it furnishes means whereby the tension of the yarn in winding may be well controlled and thereby the lay of the yarn benefited. In the formation of thebase of the package the invention pro-" vides means whereby the successive-layers.

of yarn may be so laid, oneover the other, until the full diameter of the package is secured, that each bottom coil of each layer is laid safely up and above the bottom coil ofthe preceding layer '(assumingthe yarn receiver to be upright and the yarn to be wound thereon from the bottom upward as in the preferred arrangementof parts of mechanism embodying my invention); and 7 While the mechanism accomplishes. this broadlyin the formation of the base of the package, it may be arranged to continuethe samewinding effect throughout the entire length of the package. This feature of the winding'is accomplished by increasing the gain and preferably by progressively increasing the gain throughout the formation of the base of the package; throughout the.

remainder ofthe'package, the gain should be such as to maintain the body of the packi this increase of traverse is obviously'to lay.

I of the spindle or other yarn; receiver, and

age ofsubstantially uniform diameter. To this end, I may, while constantly-increasing the traverse throughout the cop, so (control the gain as to'accomplish this result. This may be effected by providing :for'an unincreased gain throughout the body of the i'package. above the base, provided the in creasing traversebe maintained. Cooperatively with this mechanism for lncreasing the gain, mechanism is provided to increase a the traverse throughout, the formation of the base and preferably throughout the formation of the whole package. The result of each successive layer of yarn over a'slightly greater extent axially of the package;

and further, due to the constant speed in ring'frames particularly, due further to the constant speed-of the feed rolls, if each traverse is effected in the same period of time (which is accomplished by giving the primary controller of the traverse movement a I stroke constant in time and distance), the yarn eachtime will be laid in coils a little more widely separated. lIaving reference'to the utilization of such a yarn package which involves its unwinding. features, the result 1s that the increasing.

. traverse from base to nose gives reversely a decreasing taper .from nose. to base, so that the yarn withdrawn by draft axially of the package is drawnfrom a surface on the package approaching more and more nearly to a surface at right angles to the axis of the package: By this means, as the length of yarn extending from the surface wherefr'om it is being delivered to the point above the package where draft is being applied to the yarn tends to increase, and ballooning of the yarn awayfrom the axis of the package tends to increase, this tendency to increasedballooning effect is checked by the yarn drawing from a surface which tends to approach more and more nearly to a flat surface at right angles to the axis of the package; and when the yarn package is in a shuttle this described construction of package checks the'tendency of the yarn to balloon out and contact with the sides of the shuttle, and therefore tends todecrease breakage. Further, as the base of the cop isreached in the unwindingKand throughout-the whole package if and'when the increase in gain is established throughout the whole package) each bottom; coil of each. layer (having been safely'laid by means of the increase in gain over and above the bottom coil of the preceding layer) is permittedtobe withdrawn without fouling with and tending to slough off the preceding layer. These advantages thus secured in'the unwinding are of great practical importance in weaving where the yarn is subjected to 7 quick intermittent draft reaching a-s'peed of frorn'five to tenyards asecond. 1

Referring more particularly to the drawings, the builder element herein shown is a cam, as indicated at 2, in Fig.1, it being, fast upon "a shaft vl supported j upon the framing and drivenlat a preferably con- -,stant speed in [the direction of thearrow thereon,' from any suitable mechanism, such, for example, as: a worm shaft itself driven by sprocket gearing from the main'drive shaft of the spinning frame. I am enabled, because of my'invention, to drive the shaft 1 and cam 2 at a higher rate of speed than V heretofore without changing the speed at which the drawing or feed rolls and the w revolution for eachcomplete traverse of the ring rail.

The "spindle rail is represented at 3, the

its

spindles atfl, the ring rail at 5, the spinning rings at 6 and the box rail or frame of thespinning frame at 7. These parts are preferably of usual formation and con struction, the spindles being continuously rotated in one direction, preferably by bands from the usual drum, and the yarns being delivered thereto by the usual sets of drawing rolls, not shown.

Suitably mounted in the frame of the machine upon a stud or pivot 8'is a builder lever 9, preferably having a member 10 relatively adjustable with respect thereto by set screw or otherwise, as indicated at 11 and having a roll 12 engaging the periphery of the builder element 2. It will be ob-. served that the builder lever 9, 10 is mounted to rock in a plane extending longitudinally of the frame,'and this construction is preferablyemployed where the parts operate by take-up of the flexible element. I may, however, provide a lever mounted to swing in a plane transverse to the frame, and particularly if the parts operate by let off of the flexible element.

Suitably mounted in the frame of the machine, and as herein shown in a bracket 13, is a bell crank lever 1 1 having an arm 15 upon which rides the lower end of the poker arm or rod 16 depending from the ring rail 5. The lever 14: is provided with an upwardly extending arm 17, to the outer end of which is suitably secured one end of a flexible connection here shown as a plurality of chains 18. These chains are herein represented as arranged in pairs, and a suitable number of sprocket chains, bell crank levers and poker arms or rods are provided to impart a steady up and down movement to the ring rail 5, and preferably ring rail and a row of spindles are arranged at each side of the spinning frame.

In building the yarn package, the yarn is laid upon the receiver in a series of nested cones, each of which is formed during a traverse of the ring rail. in order that these traverses may extend along or with suitable relation to the receiver, an incremental gain is. imparted to the traversing mechanism, preferably between the successive traverses. In the present embodiment of the invention, both the traverse and the gain are effected through the chain or other flexible connection or connections 18. Herein, each chain 18 is represented as attached fixedly at one end to the arm 17 of the lever 14 ,and the other end thereof is connected as hereinafter disclosed to a governing device carried by the builder lever 9, 10. The longitudinal pull imparted to the chains 18 by the builder element 2 rocks the bell crank lever 14: through arcs, the angular extent and position whereof are modified, as hereinafter set forth, by mechanism acting upon said chains 18 between the ends thereof, to effect the laying of theyarn by traverses which are maintained undiminished and preferably have a regular uniform increase, and by a gain which is also maintained undiminished and which preferably progressively increases throughout at least the base of the package. The bell crank lever 1a. having arms 15, 17, I have herein termed the ring rail lifting means, for convenience of description. Such form of lifting means may be varied within the scope of my invention.

In order to secure a traverse and a gain of the character above indicated, I have provided adj unctive means coiiperating with the builder lever and connections therefrom and which may be varied within the scope of my invention, but which are preferably such that the invention may be readily applied to existing types of ring spinning frames, inasmuch as an important object of the invention is to provide a mechanism of exceedingly simple character for the purpose stated, and which may be adapted to existing types of ring spinning or other winding frames, with comparatively little change. Herein for the purpose I have mounted upon the box rail 7 a bracket 19 indicated most clearly in Fig. 2, and upon the upper end thereof have mounted upon a pivot or stud 20 a lever 21 having at its lower end a toothed segment 22 meshing with a gear 23 loose upon a shaft2t mounted in an up ward extension 25 of the builder lever 9, 10. The gear 23 is provided with a hub 26 extending through the bracket 19 (which is suitably recessed to permit the described rocking of the builder lever 9, l0 and parts carried thereby), and fast upon said hub is a disk 27 carrying a pawl 28 adapted to engagethe teeth of a ratchet 29 shown most clearly in Fig. 3 and fast upon the shaft 24:.

The said ratchet 29 is adapted,,when intermittently actuated by the pawl 28, to impart a step-by-step rotation to the shaft 24. Upon a sleeve 26 of the extension 25 is a casing 30 partially surrounding the ratchet 29, as indicated in Fig. 3, and providing means whereby the pawl 28 engages the ratchet only at or near the end of each movei'nent of oscillation of the segment 22.

It will be observed that with the pick mechanism arranged as shown, a pick takes place while the ring rail is completing the last portion of its up traverse,although my invention is not limited to such mechanism nor the described time of its operation. Since the pick mechanism in the present em bodiment of the invention effects both the traverse and the gain, it results that not only is the incremental increase in gain added just at the time when the ring rail is completing the up portion of its traverse, but also since increase in the traverse increases the general speed of the ring rail during the traverse, it follows that the traverse is speeded up just as the ring rail is completing its up-stroke. These two factors cooperate in the operation of the mechanism to secure the proper laying of the yarn by tending, first, to keep the coils of each traverse laid well above each other at the top, and second, to

reduce the number of'coils laid at the top,

that is, when the yarn is being wound upon that portion of the receiver that is of the smallest diameter, and hence when yarn breakage 1s most apt to occur. The number -of coils laid at the top portion of each traverse is reduced in the manner described,

' compensate for the inherent tendency of a 1 co-axially with the builder lever 9, 10). At.

ring spinning mechanism to lay more winds of yarn at the upper portion of each traverse,'but it also tends to compensate for the lag of the traveler at the upper portion of the up-stroke of the ring rail, and therefore results in less variation of the speed of the traveler due to this lag at the up-portion of its stroke; and not only tends to reduce causes affecting the yarn breakage, but tends to produce a yarn package wound with more uniform tension throughout.

The lever 21 carrying thesegment 22 may beoscillated in any suitable manner, but preferably by movement of the builder lever 9, 10. VI-lerein for the purpose, I have pro vided the builder lever with the arm 25 (or may mount such arm upon the rock shaft 8 its upper end, the arm 25 is provided with a lateral extension 31. The lever 21 extends upwardly beyond its pivot 20, as indicated in Figs. 2 and 3, and is there provided ;with an open slot 32 receiving a bolt 33 extending through the lever 21 and extension 31.

The relationof the segment 22 and gear 23 may be varied in any suitable manner.

Vertically mounted in the arm 25 is a threaded shaft or screw 31, shown most clearly in Fig 4, and fast thereon is a beveled gear 35 meshing with a beveled gear 36 fast upon the shaft 2%. Held from turning upon said screw34- is a nut 37, which, at the commencement of the building of the cop, is at or near the lower end of the screw 34 andis then gradually elevated'by the rotation of the screw from the shaft 24. The

nut 37 has loosely mounted therein a stud.

shaft 38 extending through and projecting at'both sides from said nut and having fast upon its ends a pair of eccentrics, here shown as scroll cams 39, 39. The ends of the flexible connections or chains 18 are fixedly attached to'the surfacesof said scroll cams by'bolts or otherwise, as indicated at 10, 40* in Fig. 5. Fast upon the'stud shaft 38 is a pinion l-l meshing with a rack a2 upon the inner'face'of a portion of the 'extension 25. Therefore, the outward travel of the nut from the fulcrum of the lever 9, 10 results in a slow rotation of the scroll cams 39, 39 in the direction of the arrow in Fig. L. Preferably the contour of the scroll cams '39, 39 is substantially such. as V indicated and maybe such as to impart any desired character of gain to the-yarn package. Preferably, itis such, that throughout at least'the base ofthe yarn package, a progressively increasing gain is imparted,

though within the scope of my invention,

any other desired character-of gain may be imparted, as, for example, a progressively decreasing or other decreasing-character of gain. 'Preferably, however, the contour of said scroll cams'is such as to maintain the gain 'undiminished throughout at least the winding of the base of thepackage. The

gradual elevation of the nut 37 and consequent change in position of the chains 18 effects a constant increase in the traverse. In the present embodiment of the invention, the pick mechanism is constant or unvarying in operation, this being an important feature ofthe inventionand one preferably employed, inasmuch as'by employing a pick mechanism of the character indicated, 1

'greatly simplify the construction of parts.

Owing to the described character of pick mechanism, the movements of the nut 37 upon the screw '31 are uniform. The gradualrotation of the scroll cams 39, 39 effects,-in the embodiment of the invention shown, a progressive increase in the gain throughout at least the base ofjthepackage,

because the described movement of the nut 37 outward or away from the fulcrum of the builder lever 9, 10 shortens by progressively increasing increments the distancebetween the point of attachment of the chains 18 to the arm 17 of the bellcrank lever and the scroll cams 39, 39 measured along the shortest line. Moreover, inasmuch as when. the ring rail .5 is in its lowermost position, the arm 15 of thebell crank lever issomewhat below, and is movingtoward the horizontal,

it follows that the linear movements imparted by the arm 15Vto the poker arm or rod 16 gradually increase in length dueto the move ment of said. arm 16 upwardly toward the horizontal, inanalogy to the increased linear 7 movements imparted by a crank when approaching thehorizontal. Such IIICIBELSBCl linear movements of the poker arm or rod 7 16 continue throughout the formation of the base of the yarn package at least. Moreover, the slow rotationof the scroll cams 39, 39, by progressively presenting to the chains 18, 18 portions of said scroll cams at increasingly greater radial distances from the stud shaft 18', supplements the outward movement of the nut 37 and changes the traversefrom a regularly increasing traverse to a progressively increasing traverse. Ob-

' viously, however, the character of the trav erse in this respect may be modified by varying the contour of the scroll cams 39, 39.

In the present embodiment of the invention, the several factors set forth combine to effect a progressively increasing gain throughout the formation of the base of the yarn package, and the continued movement of the arm 15 is not thereafter such as substantially to modify the character of the gain during the further formation of the yarn package.

Although I have referred to the increase in the traverse as constant, it will beunderstood that thereby is meant a regular or periodic increase, inasmuch as in practice the traverse is not increased at all instants of time during the operation of the mechanism, but preferably only at a certain period or part of each traverse.

After the nut 37 has been elevated by rotation of the screw 34 in the building of the yarn packages, the said nut is returned, preferably by hand, for the formation of the next set of yarn packages, Herein for the purpose I have provided the shaft 24. with a crank handle 43, shown in Fig. 3, so that by rotation of said shaft and of the screw 34, the nut 35 may be lowered to the desired extent.

It will be understood from the foregoing description that the effect of the travel of the nut 37 uponthe chains 18 is such that the arcs of movement of the builder lever 9, 10 not only gradually increase in length, providing the gradually increasing lengths of conical layers, but the said arcs of movement are gradually advanced contraclockwise so that the rods or poker arms-16 descend to an incrementally higher point, after each upward portion-of the traverse, thus providing a gain which, as previously stated, is progressively increased.

In employing the term traverse I mean a complete forward and return movement of the yarn guide orfcomplete forward or relative return movement of the same with respect to. the yarn receiver. Each return movement terminates at a distance above the commencement of the traverse measured by the extent of the gain v Preferably I form each traverse as a vibratory traverse,-by which I mean a traverse consisting of a series of advances and retrogressions. To accomplish this result, I may provide any suitable mechanism, but

herein I have represented the builder element 2 as a cam having 'a series of The cam 2 travels in the direction of the arrow thereon and at such a speed that it completes one revolution during a single complete traverse. Considering the first or any complete traverse, while the face a; is acting upon the roll 12, the yarn guiding means is moved upwardly to such an extent as to lay the yarn in an open wind to a height reaching but part way to the ultimate height of the said traverse. Thereupon, the face a becomes active and the yarn is returned in an open wind to a point slightly above the commencement of that traverse. Thereupon the face 1) becomes active and the yarn is laid in an open wind to a point slightly higher than that reached when the face a was active. Thereupon the face 6' becomes active and the yarn is laid in an open wind downwardly to a point slightly above that reached when the face a was active. Thereupon the face 0 becomes active and the yarn laid in an open wind to a point slightly above that reached when the face 6 was active, such point being the most advanced point reached. during the laying of that traverse. Thereupon the face 0' becomes active and the yarn is laid in an open wind down wardly to the point reached when the face 79 was active. Then the face 0Z becomes active, and the yarn is laid upwardlyin an open wind to the point reached when the face 6 was active. Then the face d becomes active, and the yarn is laid downwardly in an open wind to thepoint reached when the face a was active. Then the face e becomes active and the yarn is laid upwardly in an open wind to the point reached when the face a became active, and then the face 6 becomes active and the yarn is laid downwardly in an open wind to a point short of the point where the entire traverse commenced, by a distance equal to the extent ofthe gain.

Within the scope of my invention, the lengths of the faces of the builder cam 2 may be varied, so that any step or portion of a single traverse terminates at the same height as any other step or portion of the traverse or at a height differing from that reached at any other step or portion of the traverse. I have secured excellent results by providing the cam 2 with faces a, a together equaling 67 with faces 6, 5' equaling 67%;", with faces 03, d equaling 67%;", and with faces a, 0 each equaling 45. The several faces may be of unequal length, so as to prevent any portion of the traverse terminating coincidentally with any other portion thereof.

If desired, there may be an unequal number of vibratory movements on the two parts of each traverse; asfor example there may be three vibratory movements on the up portion of the traverse, and two vibratory movements on the down portion of the traverse. This may be effected by suitably shaping the cam 2 or in any. other desired manner. ments may, of course, be any other than those herein-indicated.

' Referring to the vibratory traverse mechanism and its cooperation with the pick .mechanism, I preferably provide a construction such as shown whereby the pick mechanism is actuated to cause a gain or advance of the ring rail only once for each traverse irrespective of the vibratory movements given the ring rail during the main traverse. In the mechanism as shown, the pick mechanism is so constructed and arranged as to advance the ring rail at the latter end of the upward stroke of the main traverse, the pick pawl being prevented from engaging with the ratchet during any portion of the main traverse except at such time. Gooperatively, the cam to give the vibratory traverse is so arranged that onlyone of the vibratory movements takes place in a manner to actuate the pick mechanism; that is, as shown in Figs. 1 and 3, the pick has been given in the last few degrees of rotation of the cam prior to the passage of the point B over the roll12; and after the passage of such point and before the cam has moved so that the portion of the cam d has passedover the roll, the ring rail has beenlowered so that the pick pawl has been engaged and lifted by the shield 30, and thereafter during the remaining vibratory movements of the ring rail the pick pawl remains so disengaged. V

. The form'of pickmechanism shown accomplishesthe desired objects with a very simple arrangement of parts, but I am not limited thereto.

Inasmuch as each traverse is increased over its predecessor, each traverse advances more at the top of the wind than at the bottom thereof. The effect of the described traverse and gain are to build a yarn package, which at the bottom extends from the surface of the receiver to a maximum diam? eter without laying the bottom coil of any wind or traverse on top of or' below the bottom coil of the preceding layer or traverse. The slight but continuous incremental increase inthe gain throughout at least the base of the pa'ckage,together with a direct increase in the traverse, lays the yarn so uniformly that the chase of the yarn package is formed with a straightline constituting a conical bottom in vertical cross section until the maximum diameter of the cop or other yarn package is reached. Such maximum diameter is substantially maintained until the tip of the yarn package is reached. Thus, the increase in traverse and incremental increase in gain are effective to produce and maintain a correct and. advantageous form of package. WVlnleI have re:

ferred to the increase in the traverseas con The number, of vibratory move-V nose of-the yarn package. 7 V As stated above, the precise embodiment stant, this term is employed generically or broadly to refer to a'preferably regular increase in the traverse, such increase occurring at a certain part of each traverse, or, if desired, at a certainpart of each of a series of traverses. I preferably impart the increase to the traverse and the increase to the gain during the up-stroke of the ring rail, and preferably near .the end of such upstroke and terminating with the end of the rip-stroke. Inasmuch as the builder cam employed in the disclosed embodiment of the invention rotates preferably at a constant speed, and inasmuch as the traverse is regularly increased, it follows that the speed of the ring rail is correspondingly increased, and inasmuch as the addition to the traverse and the addition to the gain are im- 7 j parted in the present embodiment of the invention at or near the end of the up-stroke of the ringrail, it follows that the speed of movement. of the ring rail is accelerated each time toward the end of its up-strokethat is, 'when'the yarn is winding upon the of the invention herein: shown provides means for controlling the gain and traverse in a form wherein the flexible element is progressively shortened or taken on. Modification of the mechanism togive the same c0ntr0l,.z'. 0., lncreasmg traverse as discussed and generally decreasing gain as discussed;

is readily secured by so arranging the outwardly moving builder nut and scroll that the flexible element is released by increasing increments as the builder nut moves out-- ward by uniform increments, being essentially the reverse of the arrangement herein shown. Further the application of the said traverse and gain-controlling mechanism to such forms of builder mechanism as shown in a co -pending application by John V. Cunniff, filed July 1, 1912, Serial No. 706,910, will be readily apparent to those skilled in the art. v

After having laid the first traverse in the manner indicated, the second traverse cornmences at a point above the commencement of the first traverse by a distance equaling the gain and the same operation is'repeated throughout the formation of the yarn package. It will be apparent that each traverse is laid in an open cross wind, which is more advantageous for unwinding than the usual wind. It-is, of course, obvious that the number of steps into whicheach traverseis in the winding-on of the yarn upon'the portion of theyarn receiver thatlis ofleastdn ameter (and by least diameter I mean the least diameter of that portion of the yarn receiver covered by each traverse of the yarn) that the lag of the traveler as the ring rail moves toward and away from the nose of the yarn package is minimized. Therefore, a more generally rapid move ment of. the ring rail per minute may be effected, so thatwith an assumed spindle speed and an assumed ring rail speed, a more open lay of the wind will be accomplished. I have previously stated that the lag of the traveler is diminished by increasing the ring rail speed, inasmuch as fewer turns of the yarn are laid at the upper end of each traverse. It will be evident that by laying the yarn as an open wind, the number of turns is further lessened, thus still further minimizing the lag of the traveler.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
